DETAILED DESCRIPTION

At least some examples in accordance with the present invention relate to systems and processes for providing improved control, monitoring and/or configuration of uninterruptible power supplies.

The aspects disclosed herein in accordance with the present invention, are not limited in their application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. These aspects are capable of assuming other examples and of being practiced or of being carried out in various ways. Examples of specific implementations are provided herein for illustrative purposes only and are not intended to be limiting. In particular, acts, elements and features discussed in connection with any one or more examples are not intended to be excluded from a similar role in any other examples.

FIG. 1 shows an on-line UPS 10 used to provide regulated, uninterrupted power in accordance with one example in accordance with the present invention. The UPS 10 includes an input circuit breaker/filter 12, a rectifier 14, a control switch 15, a controller 16, a battery 18, an inverter 20, an isolation transformer 22, a DC/DC converter 28, a user interface (UI) 30, data storage 32 and external system interface 34. The UPS also includes an input 24 for coupling to an AC power source, and an outlet 26 for coupling to a load.

The UPS 10 operates as follows. The circuit breaker/filter 12 receives input AC power from the AC power source through the input 24, filters the input AC power and provides filtered AC power to the rectifier 14. The rectifier 14 rectifies the input voltage. The DC/DC converter 28 regulates DC power from the battery 18. The control switch 15 receives the rectified power and also receives the DC power from the DC/DC converter 28. The controller 16 determines whether the power available from the rectifier 14 is within predetermined tolerances, and if so, controls the control switch 15 to provide the power from the rectifier 14 to the inverter 20. If the power from the rectifier 14 is not within the predetermined tolerances, which may occur because of “brown out” or “black out” conditions, or due to power surges, then the controller 16 controls the control switch 15 to provide the DC power from the DC/DC Converter 28 to the inverter 20.

In an alternative example, the battery is coupled to the rectifier circuit and the rectifier functions as a boost converter on-line mode of operation and on-battery mode of operation as described in U.S. Pat. No. 7,402,921, entitled “Method and Apparatus For Providing Uninterruptible Power,” issued Jul. 22, 2008, which is hereby incorporated herein by reference in its entirety.

The inverter 20 of the UPS 10 receives DC power and converts the DC power to AC power and regulates the AC power to predetermined specifications. The inverter 20 provides the regulated AC power to the isolation transformer 22. The isolation transformer 22 is used to increase or decrease the voltage of the AC power from the inverter 20 and to provide isolation between a load and the UPS 10. The isolation transformer 22 is an optional device, the use of which is dependent on UPS output power specifications. Depending on the capacity of the battery 18 and the power requirements of the load, the UPS 10 can provide power to the load during brief power source dropouts or for extended power outages.

Using data stored in associated memory, the controller 16 performs one or more instructions that may result in manipulated data, and the controller 16 monitors and controls operation of the UPS 10. In some examples, the controller 16 may include one or more processors or other types of controllers. In one example, the controller 16 is a commercially available, general purpose processor. In another example, the controller 16 performs a portion of the functions disclosed herein on a general purpose processor and performs another portion using an application-specific integrated circuit (ASIC) tailored to perform particular operations. As illustrated by these examples, examples in accordance with the present invention may perform the operations described herein using many specific combinations of hardware and software and the invention is not limited to any particular combination of hardware and software components.

The data storage 32 stores computer readable and writable information required for the operation of the UPS 10. This information may include, among other data, data subject to manipulation by the controller 16 and instructions that are executable by the controller 16 to manipulate data. The data storage 32 may be a relatively high performance, volatile, random access memory such as a dynamic random access memory (DRAM) or static memory (SRAM) or may be a nonvolatile storage medium such as magnetic disk or flash memory. In one example, the data storage 32 includes both volatile and non-volatile storage. Various examples in accordance with the present invention can organize the data storage 32 into particularized and, in some cases, unique structures to perform the aspects and functions disclosed herein. In addition, these data structures may be specifically configured to conserve storage space or increase data exchange performance.

In one example, the data storage 32 includes data structures that house one or more operational parameters. As discussed further below, these operational parameters affect the operation of the UPS 10. Some example operational parameters include, among other operational parameters, a language parameter, a display mode parameter and a menu type parameter.

In some examples, the data storage 32 holds a configuration request. In these examples, a configuration request is an indication that the UPS 10 should direct the user to configure the UPS 10 at some future time. In one example, the UPS 10 is configured to respond to pending configuration requests immediately. In another example, the UPS 10 is configured to respond to pending configuration requests during its next power-up.

Configuration requests may be generated at various times, by various events. For example, a configuration request may be generated during the manufacturing process of the UPS 10, so that the user of the UPS 10 will be directed to configure the UPS 10 as part of its initial installation. In another example, the user may use the factory defaults screen 354 which, as discussed below, allows the user to revert the configuration of the UPS 10 to a default configuration established by the manufacturer. Such a re-initialization may generate a configuration request. In another example, the user may expressly create a configuration request via a user interface. While in some examples, the configuration request is initiated by storing the configuration request in data storage 32, examples of the present invention are not limited thereto. In other examples, the configuration request is created by other actions, such as actuation of a reset button, toggling of a dip switch or reception of the configuration request via the external system interface 34.

The external system interface 34 exchanges data with one or more external devices. These external devices may include any device configured to communicate using standards and protocols supported by the UPS 10. Examples of specific standards and protocols that the external system interface 34 may support include parallel, serial, and USB interfaces. Other examples of these supported protocols and standards include networking technologies such as UDP, TCP/IP and Ethernet technologies. In at least some examples, the external system interface includes a network management card (NMC) and a USB interface.

The user interface 30 includes a display screen and a set of keys through which a user of the UPS 10 can monitor, control and configure operation of the UPS 10. FIG. 2 depicts an external view of the UPS 10 including the user interface 30. As shown, the user interface 30 includes a power button 40, a replace battery indicator 42, a warning indicator 44, an on-battery power indicator 46, an on-line power indicator 48, an interface display 50, a scroll up button 52, a scroll down button 54, an enter button 56 and an escape button 58.

The user interface 30 functions as follows. The power button 40, when actuated, will cause the UPS 10 to toggle between power-on and power-off states. According to some examples, the UPS 10 performs a series of accompanying actions to better manage these power state transitions.

The set of indicators 42, 44, 46 and 48 provide various information regarding current and prior states of the UPS 10. For example, the UPS 10 may determine by running a self-test, that the battery 18 needs to be replaced. In this instance, the UPS 10 illuminates the replace battery indicator 42 to communicate this need.

The on-line power indicator 48 and the on-battery power indicator 46 signal the current source of power to the load. An active on-line power indicator 48 signals that the UPS 10 is providing power to the load in a normal operating fashion, i.e. the source of the power is the AC received through the input 24. Conversely, an active on-battery power indicator 46 signals that the source of the power to the load is the battery 18.

In another example, the UPS 10 may determine, for a variety of reasons, that the attention of the user is needed. The reasons may include, among others, detection that the battery 18 is disconnected or that the battery 18 has been depleted by the load. In this case, the UPS 10 signals the need for user attention by activating the warning indicator 44. In addition, the UPS 10 may provide a description of the reason for the warning in the interface display 50.

The interface display 50, which can be fashioned by a variety of hardware components including Liquid Crystal Displays and Light Emitting Diodes, presents a wide variety of information to a user. This information may include monitoring information, such as the status warnings discussed above. In addition, this information may include configuration information and prompts through which the UPS 10 collects information from the user. Together, the interface display 50 and buttons 52, 54, 56 and 58 provide the UPS 10 with more flexibility in exchanging information with the user than is available using conventional UPS technology.

In one example, UPS 10 includes an interface structure that can be navigated by the user using the interface display 50 and buttons 52, 54, 56 and 58. This interface structure may include a variety of elements related to one another in various ways. For example, the interface structure may be a hierarchical menu structure. The behavior initiated by actuation of the buttons 52, 54, 56 and 58 is dependent upon the current location of the user in the interface structure, as is the information displayed in the interface display 50.

For example, the current location of the user may be an intermediate location within the interface structure, i.e. the current location connects to other elements of the interface structure. In this situation, the interface display 50 displays one of a list of the other elements of the interface structure connected to the user's current location and the buttons 52, 54, 56 and 58 are configured to provide navigational functions. In this mode, the user can move through, and cause the interface display 50 to display each element of, the list of the elements of the interface structure that are connected to the current location. More precisely, the user can move up the list by actuating the scroll up button 52 and down the list by actuating the scroll down button 54. Furthermore, the user can navigate to the element of the interface structure currently displayed in interface display 50 by actuating the enter button 56. Conversely, the user can navigate to the user's previous location in the interface structure by actuating the escape button 58.

In another example, the current location of the user in the interface structure may cause the UPS 10 to display review information to the user via the interface display 50. This review information may be any information stored within the UPS 10 and may include, among other information, configuration information, operational information and information regarding other devices in communication with the UPS 10, such as devices to which the UPS 10 supplies power. In one example, the interface display 50 displays an element belonging to a list of review information and the buttons 52, 54, 56 and 58 are configured to provide review functions. Under this configuration, the user can move through, and cause the interface display 50 to display each element of the list of review information. More specifically, and much like the navigational mode discussed above, the user can navigate up or down the list of review information by actuating the scroll up button 52 or the scroll down button 54. Furthermore, the user can navigate to the user's previous location in the interface structure by actuating the escape button 58. In at least some examples, actuation of the enter button 56, while in this mode, results in an error message explaining that the other keys are the valid keys at the user's current location within the interface structure.

According to another example, the current location of the user in the interface structure may cause the UPS 10 to prompt the user for information through the interface display 50. The information prompted for may be any information stored within the UPS 10 and may include, among other information, configuration information, information regarding the source of power into the UPS 10 and information regarding other devices in communication with the UPS 10, such as devices to which the UPS 10 supplies power, i.e. elements of the load. In this instance, the interface display 50 displays a prompt for information and the buttons 52, 54, 56 and 58 are configured to provide data entry functions. In this situation, the user can adjust the information displayed in the interface display 50 and enter responses to the prompts. More specifically, the user can change the response to the prompt using the scroll up button 52 or the scroll down button 54. For example, a user can toggle a Boolean value from true to false or from yes to no, by actuating either of buttons 52 or 54. In another example, the user can increase or decrease a numerical answer displayed in the prompt by actuating the scroll up button 52 or the scroll down button 54. In still another example, the user can scroll up or down a list of answers using the scroll up button 52 or the scroll down button 54. In addition, the user can enter the currently displayed response to the prompt by actuating the enter button 56. The user can also exit the prompt without responding to the prompt by actuating the escape key 58. Thus, the particular arrangement and function of the user interface 30 provides users with sundry advantages over conventional UPS interfaces.

The user interface shown in FIG. 2 may be implemented in other examples using different configurations of buttons, different styles of buttons and using display screens of different sizes. In one example, the interface display 50 is a touch screen interface upon which the buttons are rendered for user input. In this example, the sizes, colors and arrangement of the buttons can be altered based on a number of factors including, among others, the level of expertise of the user, the availability of the buttons to accept input and the current status of the UPS. Thus examples in accordance with the present invention allow the user interface 30 to be tailored to the requirements of a variety of users.

Although an on-line UPS has been described herein, the methods and systems described herein may be applied to other types of UPSs as well. For example, the UPS may be a line interactive UPS, which is similar to off-line and on-line UPSs in that it switches to battery power when a blackout occurs. However, when a power line sag or swell occurs, at least one type of line interactive UPS activates a tap switching voltage regulation circuit to stabilize the output voltage continuously, without consuming battery power. The tap switching voltage regulation circuit often includes an automatic voltage regulation (AVR) transformer, which operates in single boost, double boost or trim modes. One example of a line interactive UPS may be found in U.S. patent application Ser. No. 12/360,648, entitled “System and Method for Limiting Losses in an Uninterruptible Power Supply,” filed Jan. 27, 2009, which is hereby incorporated herein by reference in its entirety.

Some examples in accordance with the present invention relate to interface structures that change based on the characteristics of the environment in which a UPS employing the interface structures operates. In these examples, the UPS 10 may manipulate user interface elements to suit the level of expertise of users and accommodate particular UPS configurations. When determining a particular adaption to perform, the UPS 10 may test for the presence or absence of one or more specific operational conditions. FIG. 3 illustrates an example of an adaptive interface structure 300 in accordance with the present invention.

In the example shown, the UPS 10 activates, deactivates and modifies some of the elements of the adaptive interface structure 300 based on a variety of information. In this example, the information used to adapt the adaptive interface structure 300 includes, among other information, operational parameters stored in the data storage 32, peripherals attached to the UPS 10 and software installed on remote devices coupled to the UPS 10 via the external system interface 34. In addition, in the example shown, some elements, which are characterized herein as common elements, are not modified by the UPS and, therefore, are displayed within the adaptive interface structure 300 in any UPS operational environment. As shown, the adaptive interface structure 300 includes a main menu 302, a status screen 304, a configuration screen 306, an about screen 308, a control screen 310, a logs screen 312 and a test and diagnostics screen 314.

In the illustrated example, the main menu 302 provides access to common screens 304, 306 and 308. If the UPS 10 determines that the menu type parameter has been set to a standard value, the UPS 10 deactivates screens 310, 312 and 314. As is discussed further below, the menu type parameter is an operational parameter that can be configured by a user during the configuration of the UPS 10. Conversely, if the UPS 10 determines that the menu type parameter has been set to an advanced value, the UPS activates screens 310, 312 and 314.

In this example, the status screen 304 provides access to various screens that display a variety of information regarding the status of the UPS 10. As shown, the status screen 304 provides access to common screens 320, 322, 324, 326, 328 and 330. If the UPS 10 determines that the menu type parameter has been set to the advanced value, the UPS 10 activates screens 334, 336 and 338. Conversely, if the UPS 10 determines that the menu type parameter has been set to the standard value, the UPS 10 deactivates screens 334, 336 and 338. In addition, if the UPS 10 determines that it is connected to an external battery, the UPS 10 activates screen 332. Furthermore, if the UPS 10 determines that it is connected to an NMC, the UPS 10 activates screen 344. Further still, if the UPS 10 determines that it is connected to an external device that includes installed software, the UPS activates screen 340.

In some examples, the UPS 10 activates certain screens if specific combinations of characteristics are present in its current operational environment. For example, with continuing reference to FIG. 3, the UPS 10 activates screen 342 if software is installed on a device coupled to the UPS 10 and the menu type parameter has been set to the advanced value. In another example, the UPS 10 activates screen 346 if an NMC is installed in the UPS and the menu type parameter has been set to the advanced value. In other examples, screens may be activated if certain peripherals are connected to the UPS 10 and the menu type parameter has been set to the advanced value. The UPS 10 may consider any number of characteristics when adapting the adaptive interface structure 300 to a specific operational environment and examples in accordance with the present invention are not limited to specific structures or sets of characteristics.

Referring again to FIG. 3, the configuration screen 306 provides access to several screens that allow a user to configure a variety of parameters that control the operation of the UPS 10. As shown, the configuration screen 306 provides access to common screens 348, 352, 354 and 374. If the UPS 10 determines that the menu type parameter has been set to the advanced value, the UPS 10 deactivates screen 350 and activates screens 356, 358, 360, 362, 364, 366, 368, 370 and 372. Conversely, if the UPS 10 determines that the menu type parameter has been set to the standard value, the UPS 10 activates screen 350 and deactivates screens 356, 358, 360, 362, 364, 366, 368, 370 and 372. In addition, if the UPS 10 determines that it is connected to an NMC and the menu type parameter is set to the advanced value, the UPS 10 activates screen 376.

According to the illustrated example, the about screen 308 allows users to access a variety of screens that display information concerning components of UPS 10. As depicted, the about screen 308 provides access to common screens 378 and 380. If the UPS 10 determines that the menu type parameter has been set to the advanced value, the UPS 10 activates screens 385, 386, 387, 388 and 389. Additionally, if the UPS 10 determines that an NMC is installed within the UPS 10, the UPS 10 activates screen 382. Further, if the UPS 10 determines that software is installed on a connected external device, the UPS 10 activates screen 384.

As shown in FIG. 3, the control screen 310 provides users with access to screens that control the operation of the UPS 10. As depicted, the control screen 310 provides access to common screens 390 and 391. If the UPS 10 determines that the menu type parameter has been set to the advanced value, the UPS 10 activates screens 392, 393, 394, 395 and 396.

In the example shown, the logs screen 312 provides access to logged event information. The UPS 10 activates screens that provide logging information if it determines that the menu type parameter has been set to the advanced value. If, however, the UPS 10 determines that the menu type parameter has been set to the standard value, the UPS 10 deactivates the log screens.

According to the example shown in FIG. 3, the test and diagnostics screen 314 provides access to screens that allow a user to verify that the UPS 10 is in proper operational condition. If the UPS 10 determines that the menu type parameter has been set to the advanced value, the UPS activates screens 397, 398 and 399. Conversely, if the UPS 10 determines that the menu type parameter has been set to the standard value, the UPS 10 deactivates screens 397, 398 and 399.

The various screens depicted in FIG. 3 function as follows. The behavior of the main menu screen 302 depends on the value of the menu type parameter and a display mode parameter. If the UPS 10 determines that the display mode parameter is set to the auto off value, then the UPS 10 adapts the main menu screen 302 to display a blank screen after a predetermined period of time. In the alternative, if the UPS 10 determines that the display mode parameter is set to the always on value, the UPS 10 adapts the main menu screen 302 to continuously display information. In either case, the information displayed by the main menu screen 302 is affected by the value of the menu type parameter as discussed below.

For example, if the UPS 10 determines that the menu type parameter is set to the standard value then the UPS 10 adapts the main menu screen 302 display an indication of the remaining power left in the battery 18 and an indication of the amount of load on the UPS 10. If the UPS 10 determines that the menu type parameter is set to the advanced value then the main menu screen 302 is adapted to cycle through a set of six screens. These screens display a set of indications including indications for the currently utilized source of power for the UPS 10, e.g. on-line or on-battery, the remaining power in the currently utilized power source, the efficiency of the UPS 10, current status of the outlet groups of the UPS 10, input and output power, the amount of power being drawn by the load, the remaining power capacity, the amount of remaining runtime of the battery and the reason for the last transfer of power between power sources. From the main menu screen 302, a user can move through any of screens 304, 306, 308, 310, 312 and 314 that are active by actuating the scroll up button 52 and the scroll down button 54.

The software protocol information screen 342 displays an indication of the physical connection type, for example network, serial, universal serial bus, etc. . . . , and the protocol, for example micro-link, used by the software. The NMC information screen 344 displays the IP address, IP subnet mask and default gateway used by the NMC. The NMC device information screen 346 displays an indication of the probe temperature, probe humidity and contact sensor status of the NMC.

In the illustrated example, the screens that are accessible via the configuration screen 306 allow the user to modify the default configuration of the UPS 10. The default configuration of the UPS 10 may associate a set of default values with a set of operational parameters. In one example, each of the screens accessible via the configuration screen 306 is associated with at least one operational parameter of the UPS 10 and allows the user to review a set of values that are assignable to the associated operational parameter. The values assigned to the operational parameters may control the operation of the UPS 10. In one example, the user can move through the set of values by actuating the scroll up button 52 and the scroll down button 54. In addition, the user can assign the currently displayed value or values to the associated operational parameter or parameters by actuating the enter button 56. In response, the UPS 10 can store the values assigned to the operational parameters in data storage 32. Also, the user can change position in the adaptive interface structure 300 to the configuration screen 306, without changing the value assigned to the associated operational parameter, by actuating the escape key 58.

In the example shown in FIG. 3, the screens that are accessible via the configuration screen 306 provide access to a variety of operational parameters. The UI language screen 348 prompts the user to select the language in which the UPS 10 will display information. The power quality screen 350 prompts the user to indicate the quality of power, for example “good,” “fair” or “poor,” supplied to the UPS 10. In response, the UPS 10 determines a plurality of values to assign to a plurality of operational parameters. For example, the UPS 10 can assign, based on the indication of power quality, values to upper and lower power transfer points, a value to sensitivity to changes in power, a value to tolerance shown to deviations from a benchmark frequency and a value to beeper duration. Additionally, in an example where the UPS 10 is a line interactive UPS, the UPS 10 can assign, based on the indication of power quality, a value to the AVR operating mode. AVR operating modes may include, among other operating modes, green, single boost, double boost and trim modes.

In other examples, the UPS 10 can determine other values for these and other operational parameters in response to information entered by the user. In one example, the UPS 10 can adjust the values assigned to the upper and lower transfer points, the sensitivity and the frequency tolerance based on an indication that the user wishes to prolong the useful lifespan of the battery. In another example, the UPS 10 can assign different values to these operational parameters based on an indication that the user wishes to prolong the duration of time that the battery 18 can power the load, i.e. the runtime of the battery. According to another example, the UPS 10 can adjust the frequency with which the UPS 10 conducts a self test in response to a user indication that the user wishes to prolong the useful lifespan of the battery. Thus examples in accordance with the present invention provide technical expertise to standard users by tailoring the complex configuration of the UPS 10 in response to readily ascertainable information regarding the operational environment of the UPS 10.

Returning to FIG. 3, the menu type screen 352 prompts the user to select the type of interface structure and content displayed by the UPS 10. In one example, the values that are assignable to the menu type parameter include a standard value and an advanced value. As discussed above, the adaptive interface structure 300 is adapted based on a variety of information including the value assigned to the menu type parameter. More specifically, in response to the menu type parameter being assigned a specific value some screens included in the adaptive interface structure 300 are deactivated and others are activated. In addition, some screens are simplified with less dense and easier to read information. For example, some abbreviations are expanded and some information, such as indications of deactivated screens, is removed from screens that would display the information under a different configuration. Once values have been established for the various operational parameters, the UPS 10 can apply the values to control its operational behavior. For instance, the controller 16 can adapt the interface structure to comply with the value assigned to the menu type parameter or adjust the behavior of the user interface 30 to comply with the value assigned to the display mode parameter.
